Abstract
The invention relates to an environment-friendly brick produced from combustion slag of oil-bearing sludge reclaimed coal and a manufacturing method thereof. The invention is characterized in that slag powder, which is obtained by combusting reclaimed coal made of oil-bearing sludge and coal gangue powder, waste clinker powder, fly ash powder, Portland cement, calcium oxide, calcium sulfate, sodium chloride, colophony thermopolymer, calcium sulfonate, sodium sulfate, sodium aluminate, water and the like are used as raw materials. The method comprises the following steps: mixing the raw materials into a moisturized state by using a double-shaft mixer, carrying out extrusion molding in a mechanical vibration mode, steam-curing, and naturally cooling to obtain the environment-friendly brick produced from combustion slag of oil-bearing sludge reclaimed coal. The raw materials of the invention can also be used for making hollow building block, crown wall bricks, square bricks and pavement bricks with different specifications. The product has the advantages of light weight, high strength, no pollution, low cost and good benefit, and conforms to the environment protection development low-carbon economic requirements of energy saving and emission reduction.
Description
Technical field
The present invention relates to a kind of environmental protection brick of producing with oily sludge regeneration coal combustion waste residue; Specifically it is with multiple oily sludge; The waste residue of regeneration coal after burning of processing for primary raw material through dehydration back and gangue, incineration of refuse flyash etc. is the environmental protection brick of main material production, belongs to the refuse disposal field.
The invention still further relates to the manufacturing approach of this oily sludge regeneration coal combustion waste residue environmental protection brick.
